CAT5121TBI-50GT3 Datasheet PDF - ON Semiconductor

●CAT5121 linear-taper digital POT performs the same function as a mechanical potentiometer or a variable resistor. This device consists of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a 2-wire up/down serial interface.The CAT5121 is configured as a variable resistor. See Three resistance values are available: 10 kΩ , 50 kΩ and 100 kΩ.
